I'm not sure why, but the doap has been dropped from
http://svn.apache.org/repos/asf/jmeter/site/doap_JMeter.rdf again.
It does not belong in the source tree, but does not necessarily have
to be on the site so long as the project file is updated accordingly.
Github user FSchumacher commented on the issue:

Thanks for your contribution and sorry we took so long to give a bit of
feedback.
I would advise you to discuss the introduction of this feature on the dev
mailing list first.
